![Page 5: Electronic Portfolio Technology Options options.pdf•Web design: Dreamweaver, Netscape Composer •Graphics tools: Adobe Photoshop, Illustrator •Audio and video: iMovie •Print](https://reader034.vdocument.in/reader034/viewer/2022051813/6031bd7d3f1c1c54724e91e1/html5/thumbnails/5.jpg)
Generic Tools Disadvantages
• Many students and faculty members don’tknow these tools already; steep learning curve
• Students need access to expensive desktopsoftware and fast computers
• Time consuming to produce (and consume)
• Privacy challenges

Commercial Tools Best Practices
• Survey the range of portfolio practices you mightneed to support before choosing a tool
• Develop a CFP based on your needs, not availablefeatures
• Look for open standards support (IMS and OKI)• Schedule lots of demos, even if you’re not the sole or
primary decision maker• Budget for both software and services

Open Source Tools Advantages
• No (or low) licensing costs
• Commercial advantages: Ease of use, features, andintegration with other systems
• Customizable in-house
• Factored architecture (OSPI)
• Technical support and vendor consulting
• Support from community (Linux)
• Direction of development determined by community

Open Source Tools Disadvantages
• Direction of development determined bycommunity
• Proprietary format
• Other people’s code is harder to work with
• You support it yourself
![Page 14: Electronic Portfolio Technology Options options.pdf•Web design: Dreamweaver, Netscape Composer •Graphics tools: Adobe Photoshop, Illustrator •Audio and video: iMovie •Print](https://reader034.vdocument.in/reader034/viewer/2022051813/6031bd7d3f1c1c54724e91e1/html5/thumbnails/14.jpg)
Open Source Best Practices
• All the commercial best practices apply
• Engage the community before you commit
• Formalize your relationships with the keyplayers (CHEF -> SAKAI example)
• Find a way to contribute early and often
• Consider partnering with other institutions
![Page 15: Electronic Portfolio Technology Options options.pdf•Web design: Dreamweaver, Netscape Composer •Graphics tools: Adobe Photoshop, Illustrator •Audio and video: iMovie •Print](https://reader034.vdocument.in/reader034/viewer/2022051813/6031bd7d3f1c1c54724e91e1/html5/thumbnails/15.jpg)
Open Source Example
• Open Source Portfolio
• Designed for multiplicity
• Designed for connectedness
• Sophisticated assessment and reporting
• http://www.theospi.org/
![Page 16: Electronic Portfolio Technology Options options.pdf•Web design: Dreamweaver, Netscape Composer •Graphics tools: Adobe Photoshop, Illustrator •Audio and video: iMovie •Print](https://reader034.vdocument.in/reader034/viewer/2022051813/6031bd7d3f1c1c54724e91e1/html5/thumbnails/16.jpg)
OSP 2: Multiplicity
•Collection– Artifacts - files, reflections, comments …– Relationships - reflection on, attests to, evidence of, etc.
•Design– Visual design– Hypertext
•Guidance– Matrixes and rubrics– Wizards and checklists– Analytical tools: search and query
![Page 17: Electronic Portfolio Technology Options options.pdf•Web design: Dreamweaver, Netscape Composer •Graphics tools: Adobe Photoshop, Illustrator •Audio and video: iMovie •Print](https://reader034.vdocument.in/reader034/viewer/2022051813/6031bd7d3f1c1c54724e91e1/html5/thumbnails/17.jpg)
OSP 2: Connectedness
• Common Interest Groups (CIG)– Anyone can create CIGs, guidance, and designs
– Collaboration tools through Sakai
• Libraries and templates– Anything can be shared with any CIG
• Interoperability– Easier integration with other systems through open standards
– Import and export using IMS ePortfolio
